pub struct Prepare { /* private fields */ }Implementations§
Source§impl Prepare
impl Prepare
Sourcepub fn into_prototype(self) -> VirtualMachinePrototype
pub fn into_prototype(self) -> VirtualMachinePrototype
Turns back this virtual machine into a prototype.
Sourcepub fn memory_size(&self) -> HeapPages
pub fn memory_size(&self) -> HeapPages
Returns the size of the memory, in bytes.
Sourcepub fn read_memory(
&self,
offset: u32,
size: u32,
) -> Result<impl AsRef<[u8]>, OutOfBoundsError>
pub fn read_memory( &self, offset: u32, size: u32, ) -> Result<impl AsRef<[u8]>, OutOfBoundsError>
Copies the given memory range into a Vec<u8>.
Returns an error if the range is invalid or out of range.
Sourcepub fn write_memory(
&mut self,
offset: u32,
value: &[u8],
) -> Result<(), OutOfBoundsError>
pub fn write_memory( &mut self, offset: u32, value: &[u8], ) -> Result<(), OutOfBoundsError>
Write the data at the given memory location.
Returns an error if the range is invalid or out of range.
Sourcepub fn grow_memory(
&mut self,
additional: HeapPages,
) -> Result<(), OutOfBoundsError>
pub fn grow_memory( &mut self, additional: HeapPages, ) -> Result<(), OutOfBoundsError>
Increases the size of the memory by the given number of pages.
Returns an error if the size of the memory can’t be expanded more. This can be known ahead
of time by using VirtualMachinePrototype::memory_max_pages.
Sourcepub fn start(
self,
function_name: &str,
params: &[WasmValue],
) -> Result<VirtualMachine, (StartErr, VirtualMachinePrototype)>
pub fn start( self, function_name: &str, params: &[WasmValue], ) -> Result<VirtualMachine, (StartErr, VirtualMachinePrototype)>
Turns this prototype into an actual virtual machine. This requires choosing which function to execute.

Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
